The Navigator allows you to browse your topic maps in a convenient web
interface with no need for programming or configuration. Ontopia will be
adding support for the XTM (XML Topic Map) DTD as soon as its been
finalized; in the meantime an XML DTD (Document type definition) defined
by Ontopia is required. If your topic map is valid against the following DTD
(http://www.ontopia.net/ontopia/tmdtds.html) you can load it into the
navigator and start browsing it right away.

The free version of the Navigator is restricted to only accept topic
maps smaller than 5 kilotao in size. This means that the topic map can
have no more than 5000 topics, associations and occurrences. The
Navigator will expire on 15 April 2001 and is intended for
non-commercial use. Shortly before the expiry date, you will be able
to upgrade to a trial of our 1.0 version of the software.

Enjoy your journey into topic space!
